What jobs everyone has 19 years later?
I was curious about that one, too. Did Harry become an auror, as he had wanted? It seems the logical job for him. I would expect Mrs. Potter to be a stay-at-home mom, like her mother. Mrs. Ron Weasley, on the other hand, I would expect to hold a position suited to her talents. I don't know what Ron would be doing.
Percy resigned. Did the new minister give him his job back, or did he fill Fred's place at the joke store?
What about Kreacher and the house elves? Did Harry Keep Kreacher on as servant or free him?
Who in the hell would marry Malfoy?
Pansy Parkinson always had the hots for him, didn't she?
How do they sort kids if the sorting hat burned?
The sorting hat was already seriously patched and repaired. I don't think a few more stitches and some new fabric would hurt. As they say at Lloyd's: A boat remains the same boat even if every timber is replaced, as long as it is built on the lines of the original. I would expect the same to be true of sorting hats. You might check with the hat's underwriter.
How did Neville get the Sword of Gryffindor if the Goblin had it?
The hat and the sword both belonged to Godric Griffindor, so I would suspect that there was some bond between them. The hat was able to deliver the sword to Harry in the Chamber of Secrets, I doubt that it would have trouble finding the sword wherever it was. I guess it would come down to the question of whose magic was stronger: Griffindors or the goblins.
My question is whether or not Harry Kept his word and returned the sword to the goblin after peace was restored. I know the goblin didn't act honourably at the vault, but he did fulfil his part of the bargain.
How could Tom Riddle be arrogant enough to think he was the only one that knew about the Room of Requirement for hiding the Diadem? It is described as having so many objects that kids have stored there over MANY years.
That does seem a bit hard to figure. I would have expected him to hide it in the Chamber of Secrets. That would seem logical, since he was the only one who was supposed
to be able to open it.
Of course, there were a lot of loose ends Ms. Rowling had to tie up, and I think she did an admirable job of doing so. I think the rambling in the wilderness was necessary to show Harry's personal struggle with the greed that was Dumbledore's downfall after finding out about the Deathly Hallows. Remember that he wanted to use them to make him invincible, which would have spelled disaster for him had he done so. Dumbledore says that he wanted Hermione to sway him to reason, which she (and the death of Dobby) seem to have done. Of course, learning the truth from Snape helped, as well.
Surprises for me in the book:
1. Dumbledore was dead. I thought he was in hiding. He had just told Malfoy that being dead was a great way to hide, so I thought he had tipped his hand.
2. Crookshanks didn't appear in the book. I had thought that Crookshanks was Regulus Black as an animagus. He seemed to recognize Sirius in Book 3, and helped him throughout the series. He appeared at the Magical Menagerie about the same time as Regulus apparently vanished, and Regulus body had not been recovered. It all fit, at least in my mind.
